In the meantime, the researchers launched Permasense in to continue developing and marketing the product for use with other oil firms. According to Collins, BP intends to install thousands of sensors over the next few years.
BP did not respond to requests for comments. Thus far, one refinery is installing more than 1, sensors, while the others are starting with fewer units. Each sensor sends ultrasonic waves into a pipe wall, and measures the waves reflected back.
The walls of uncorroded pipes range from 3 millimeters to 25 millimeters 0. Each sensor's radio chip transmits its unique ID number and the measurement data at preset intervals. Permasense's Peter Collins The closest neighboring Permasense unit receives that RF signal the tag's maximum transmission range is about 55 yardsand then transmits that sensor's data to the next device, along with its own information, thereby creating a mesh network.
All data is received by a gateway wired to a PC. Permasense software, residing either on the PC or on a server hosted by BP, stores that information, interprets it and makes it available to engineers and refinery management via the Internet.
To modify the sensor unit so that it can sustain the high pipe temperatures—which can exceed 1, degrees Fahrenheit degrees Celsius —the sensor and RFID hardware is housed in a plastic casing and attached to the pipe wall via a set of legs, about 12 inches in length, through which the ultrasound waves are transmitted and received.
The outer tips of those legs are attached to a mounting welded directly to the pipe. In the future, Collins says, each of BP's refineries could use tens of thousands of sensors.
Permasense has been marketing the system to other oil companies since the fall ofand is currently in conversations with those interested in employing the technology.1 Ateneo de Manila University School of Science and Engineering Health Sciences Program Thesis Abstracts Monograph This thesis proposes the use of a ‘whole of system’ approach to the analysis of security in Radio Frequency Identification (RFID) systems and introduces a reference model for this purpose.
